The closure phase in focused on relaxation Wait list control group: 14 participants Wait‐list participants did not receive any psychological or pharmacological treatment. They were informed that at the end of the study, they could receive psychological help from the research team
Outcomes	IES‐R scores for the EMDR group and the wait list control group. Symptoms of depression as measured with the Beck Depression Inventory‐II (BDI‐II)
Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Quote: "For the allocation of participants to different treatment groups, a computer‐generated random number list was used. Participants were randomly assigned on a 1:1 basis to the EMDR or wait‐list group"
Allocation concealment (selection bias)	Unclear risk	No information provided
Blinding of participants and personnel (performance bias) All outcomes	High risk	Quote: "The participants and the therapists were aware of the allocated arm"
Blinding of outcome assessment (detection bias) All outcomes	Low risk	Quote: "The outcome assessors were kept blind to the allocation"
Incomplete outcome data (attrition bias) All outcomes	Low risk	No one withdrew from the study
Selective reporting (reporting bias)	Low risk	Rating scales listed in the "Methods" section were reported in the "Results" section (IER‐R and BDI‐II)
Therapist qualification	Low risk	Trained psychologists
Treatment fidelity	Low risk	Quote: "The supervisor personally observed a minimum of one session with each therapist (with the permission of the participant). The supervisor checked during live and normal one‐on‐one and group supervision sessions whether the therapists were complying with the 8 Phase EMDR standard protocol. Treatment fidelity was supported by the supervisor, who attended at least one session of each therapist"
Therapist/investigator allegiance	High risk	Psychologists were trained at EMDR level I by the second trial author, who is an EMDR Institute‐accredited trainer. No further information provided
Other bias	Unclear risk	Sponsorship bias cannot be ruled out
